Could I be pregnant?

Mikyla • Engaged, and have a 7 month little boy 😊
Me and my husband decided we wanted to have another baby, I stopped taking birth control last month when I was in my fertile stage, we also had unprotected sex. My last period was April 8-14. I haven't got my period yet, I don't really feel any different other than fatigue, and appetite increase. Could I be pregnant? Also, I took a pregnancy test at the beginning if May and it was negative, not sure if that was too early to take it though
